NON-REFILLABLE REGEPTACLE.

Patented Dec. 24, 1907.

Application filed April 1, 1907- Serial No. 365.695.v

To all whom it may concern:

Be it known that we, RoY N. CUNNING- HAM and JOHN W. MoPHnRsoN, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful lmprovements in Non-Refillable Receptacles, of which the following is a specification.

Our invention relates to non-refillable liquor receiving receptacles and has for its object the provision of a device of this character which may be very cheaply made and which after being once emptied, cannot be refilled.

Further objects and advantages of the invention will be set forth in the detailed de* scription which now follows: v

In the accompanying drawing: Figure 1 is a vertical section of a nonsrefillable rece tacle, constructed in accordance with t e invention, and, Fig. 2 is a plan view of said receptacle.

Like numerals designate corresponding parts in both of the figures of the drawing.

Referring to the drawing, the numeral 5 designates a glass body portion which is provided with a closed concaved top 6.v An annular groove 7 is formed in the wall of this receptacle, of such configuration asto produce the sharp shoulder 8 (see Fig.` 1). body 5 is open at the bottom. A piston-like bottom 9 also of glass, is annularly grooved as at 10 for the reception of a preferably cork packing ring 11. The upper face 12 of the bottom 9 is concaved and conforms to the curvature of the lower side of the top 6. An outlet tube 13 is in communication with the interior of the body portion 5 as at 14. This tube has a downwardly extending portion 15 at one side of the receptacle and an upwardly extending portion 16 at the opposite side of the receptacle, these two portions being connected by a horizontally disposed tube 17 and the portion 16 terminating in a spout 18.

The operation of the device is as follows Before the bottom 9 is placed in position, the receptacle is held in an inverted position and filled with any desired liquid. Since the portion 17 of the outlet tube, lies below the top of the bottom 9, none of the liquid can pass through the tube during this filling operation. After the desired quantity of liquid has been placed inthe receptacle, the bottom 9 is forced into position, the cork pack- The ing ring 1l being tightly compressed in its groove 10 when this is`done. It is impossible after this point has been reached to remove the liquid from the bottle except by forcing the bottom 9 bodily into the receptacle 5, this bottom then acting much after the manner of a piston to force the liquid through the outlet tube 13 and from the spout 18. The convex lower face of the top 6 enters the concaved top 12 of the bottom 9, said concaved top of the bottom collecting the last few drops of liquor at a central point, from whence it may readily be forced through the tube 13 as the bottom 9 is forced into contact with the lower face of the top 6. When the bottom 9 reaches its upward limit of movement, the ypacking ring 11 expands into the groove 7 and is engaged by the sharp shoulder 8 to prevent retrograde movement of the bottom. The body portion 5 is now practically a bottomless receptacle and is not ada ted to again serve the purposes set forth, or the bottom 9 closes the mouth of the outlet tube13.l It is impossible to remove this bottom 9 without breaking the receptacle 5, for this bottom will be made of heavier glass than the receptacle 5 and any attempt to break the bottom 9 to remove it, will result in breaking the main receptacle.

From the foregoing description, it will be seen that simple and efficient means are herein provided for accom lishing the objects of the invention, but w 'le the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

Vhat we claim, is: c

1. In a device of the character described, the combination with a body portion closed at the top and open at the bottom, of an outlet tube leading from the upper portion of said rece tacle to a point adjacent the lower end of t e receptacle, said tube then being returned to a point adjacent the upper end of the receptacle, and a piston-like bottom disposed within the receptacle.

2. In a device of the character described, the combination with a body portion closed at the top and open at the bottom, of an outlet tube leading from the upper portion of said receptacle to a point adjacent the lower end of the receptacle, said tube then being returned to a point adjacent the upper end of the receptacle, a piston-like bottom disposed Within the receptacle, and means for locking said piston-like bottom against retrograde movement after it reaches its limit oi movement toward the top of the receptacle.

3. A non-reiillable receptacle, comprising a body portion open at the bottom and closed at the top, an outlet tube leading from the upper portion of the receptacle, and a iston-like bottom for the receptacle Whic is slidablyl disposed Within said receptacle, the lower face of the top being convex and the upper face of the bottom being concaved.

fi. A non-reillable receptacle, comprising a body portion open at the bottom and closed at the top, an outlet tube leading from the upper portion of the rece tacle, a piston-like bottom for the receptac e which is slidably disposed Within said receptacle, and means Jfor locking said piston-like bottom against retrograde movement after it reaches its limit of movement toward the top of the receptacle, the loWer face of the top being conveX and the upper face of the bottom being concave.

5. In a device of the character described, the combination With a body portion closed at the to and open at the bottom, of an outlet tube lleading from the tube Which extends down one side of the receptacle to a point adjacent the bottom thereof, then partially around said receptacle and then up to a point above the top of the receptacle, there being an annular groove formed in the Wall of the receptacle adjacent the top thereof, a pistonlike bottom slidably disposed Within the receptacleJ and an annular packing ring carried by said bottom Which is adapted to expand into said annular groove when the bottom reaches its limit of movement toward the to 1in testimony whereof We aiX our signatures in presence of tWo Witnesses.
